Every day is Prime Day for Jeff Bezos

Amazon shoppers are getting ready to celebrate Prime Day on July 12. But every day is Prime Day for Amazon investors — and especially Amazon CEO Jeff Bezos.

Amazon’s stock hit a new all-time high on Thursday. The company has held up well this year, gaining nearly 10%, despite all the Brexit doom and gloom and worries about a sluggish global economy. The continued success of Amazon (AMZN, Tech30) has also made Bezos one of the world’s wealthiest people.

In fact, he’s now worth about $ 64 billion, according to both Forbes and Bloomberg — which have rival billionaire trackers. That makes him the fourth-richest person on the planet.

Of course, most of Bezos’ wealth is a result of Amazon’s success. He owns 17% of the company, which is now worth $ 346 billion.

Bezos has bigger fish to fry than Tesla’s (TSLA) Musk and Trump. If Amazon shoppers click like crazy on Prime Day — and help boost sales and profits — then Bezos may soon pass none other than Warren Buffett in the world’s richest rankings.
